    摘要: A rotating anode structure for an X-ray tube is provided, having a lightweight target anode. A carbon-carbon composite target substrate has constituents and weave geometries. A refractory metal focal track layer is deposited on the substrate to produce X-rays. An interlayer is disposed between the focal track layer and the substrate to relieve thermal expansion mismatch stresses between the carbon-carbon composite anode target substrate and the refractory metal focal track layer. The interlayer is a rhenium interlayer and the focal track layer is typically a tungsten-rhenium focal track layer.

    摘要: An x-ray tube includes a cathode which supplies electrons that bombard a target material to produce x-rays. The target is supported on a rotating anode that includes fins covered with a high emissivity material. An envelope surrounds these elements and provides a vacuum chamber in which they operate. A receptor is mounted to the envelope and includes fins which mate with the anode fins to enhance the radiation of heat from the rotating anode. A cooling liquid is pumped through the receptor.
